Product Overview
Potter & Brumfield KRPA14AG-24V 3PDT General Purpose Relay with Clear Dust Cover
Condition
New. The relay photographed for this listing is clean and shows no signs of installation: the clear plastic dust cover is intact and free of cracks, the few plug-in blade terminals that show at the edge of the frame read as bright while the rest are turned away from the camera, and the internal contact assembly and coil are plainly visible through the cover. A few dust specks sit on the outside of the cover from shelf storage. The cover carries a printed black contact schematic, a UL mark, and the rating line 3/4HP. 20A. 120VAC. 1PH. Two are in stock and the relay is sold each, so the photo is representative of what ships rather than a picture of a lot.

Product Overview
The KRPA14AG-24V is a Potter & Brumfield KRPA series general purpose relay, listed here as 3PDT with a 24V coil and 10A contacts. It is the plug-in style the KRPA line is known for: blade terminals that drop into a matching socket so the relay can be swapped without touching a single wire, under a clear cover that lets a technician watch the armature pull in instead of guessing. The cover of this piece is silkscreened with its own contact schematic and a motor rating line reading 3/4HP. 20A. 120VAC. 1PH, alongside a UL mark. Potter & Brumfield relays of this vintage were sold under the AMF corporate umbrella, which is why the brand reads as Potter & Brumfield / AMF here. The part number is also written KRPA-14AG-24V in some catalogs and cross-reference lists.

Applications
- Maintenance electrician replacing a failed KRPA relay in an existing machine control panel without rewiring the socket
- Panel builder who needs three independent switched circuits from one 24V control signal
- HVAC or pump technician keeping a legacy 120VAC control circuit running on original-style parts
- Restorer or hobbyist building a control box who wants a relay whose contacts can be watched through the cover during troubleshooting
Frequently Asked Questions
Is the 24V coil AC or DC?
Not confirmed. The listing specifies a 24V coil and nothing on the visible face of this relay states AC or DC. Check the KRPA series datasheet for the AG suffix against your control voltage before installing.
The cover says 20A but the listing says 10A - which applies?
Both figures are reported here exactly as we have them: 10A is the general purpose rating this relay has always been listed under, and 3/4HP. 20A. 120VAC. 1PH is the motor load line printed on the dust cover in the photo. Manufacturer relay ratings routinely differ by load type, so size your circuit from the KRPA series datasheet for your specific load rather than from either number alone.
Does a socket come with it?
No. What ships is the relay only, a unit of the same stock the photo represents. The blade terminals are made to plug into a matching KRPA series socket, and no socket, hold-down clip, or mounting hardware is included.
Has it been powered up and tested?
It has not been bench tested here. It is sold as new stock, judged by the intact dust cover and the clean internals visible through the case. If your application needs a verified pull-in voltage, plan to check it on the bench first.
Why buy this single relay here instead of chasing a surplus lot or an auction pallet?
Because you can see what it is. The stock is photographed, the cover markings are legible in the picture, its contact arrangement and coil voltage are stated, and it is priced and sold as one relay - not as an unknown box of mixed coils you sort on your own bench and hope contains the 24V unit you actually need. Two are in stock. Shipping is a flat $8, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
A relay that wears its own wiring diagram on the outside, printed right on the cover so the next person into the panel does not have to go looking for the print. Plug it into its socket and let it get back to closing three circuits at once.
